Maybe (not saying it did or didn't happen) when you told someone about your condition and they responded with "so sorry, if I can do anything let me know" you saw that as just a polite response? If when you hear something like that just say thank you and ask "do you really mean that? right now there is nothing, but it would be nice to know I can call one you if need arises"
put them on stand-by. some people would love to help, just don't know how.
also, I don't know where you live, but here in California we have charities that will bring good healthy food to you, and your family, daily while you recover.
There are a lot of good people out there that would love to help but you may have to reach out and I know that is hard when you are ailing. I hope you are recovering and will be well soon.
positive thoughts your way.

I can kind of relate. I’ve had one person help by moving my bins down my driveway (5 metres) to the kerb because of the slope..I’m on permanent crutches with nerve damage and peripheral neuropathy so it’s something I can’t do. They moved away so I now argued with local council saying the inspector who drives around doling out ‘do this and don’t do that’ letters can do something nice while there out bothering the neighbourhood like a wasp looking for a place to start a nest, like move my bins on bin day, considering my taxes pay them 🤭
It’s working so far.
Besides that, I’ve only had those people who grin in decidedly uncomfortable ways while quietly saying with an air of forced politeness an ingenuous offer of help - very generic, nothing specific - to placate themselves for their own discomfort when succumbing to social conformity in offering help.
Otherwise (besides the bins, which I showed much appreciation with several home baked meals and treats each week in return), I’ve never actually had anyone offer genuine practical help, ever.
Mostly - if it’s not those awkward social conformities - people say you don’t look like you need any help, or, you’re always doing so much for everyone else so someone like you wouldn’t need any help, or you’re built like a man (I take that to reference my statuesque height) so you’ll be right to do it on your own…etc. I mean, try cleaning your house, sweeping your yard, cooking and carrying a meal or a drink, doing your laundry, bed sheet changes, carrying groceries, etc, on crutches..permanently..and then open doors for others, move out the way for people staring at their phone and dawdling into you on the street, sidestepping people walking out onto the street without any caution..yep, I’m good thanks - I got this. You just keep on your merry way and I’ll keep a look out as I always do 🤦🏻‍♀️
I think if I ever had someone help me I’d fall over in a complete cardiac arrest, die and end up trying to explain what just happened at the pearly gates, while being asked but what could’ve you done for them before you dropped off the perch and rolled up here on your noisy crutches that squeak worse than the last time we couldn’t find the oil can for these giant gold yard ornaments? 😁
(By the way, I have full respect for God - I do believe He has a sense of humour, and I’m made in His image 😉).
